1. Which of the following statements best defines specific heat capacity?
The amount of heat required to change the state of a substance.
The amount of heat required to raise the temperature of 1 kg of a substance by 1 Kelvin.
The total heat content of a system.
The rate at which heat is transferred.
2. Water has a high specific heat capacity. This property is crucial for:
Its ability to dissolve many substances.
Regulating Earth's climate and body temperature.
Its density changing with temperature.
Its ability to conduct electricity.
3. The formula for calculating heat transfer is Q = mcΔT, where Q is the heat energy, m is the mass, c is the , and ΔT is the change in temperature.
4. Materials with low specific heat capacity heat up and cool down than materials with high specific heat capacity.
5. Explain why deserts experience extreme temperature fluctuations between day and night, while coastal regions have more moderate temperature changes.
